  • Best 8 inch on the market
Amazing 8 inch subwoofer, make sure it is in a .75 Cube port enclosure with 14 in of port length or else you will have mechanical issues over time. I Recommend custom enclosure not a prefabricated box’s on here.

  • More like a scam to me.
If you try to return the item to the company they will take there sweet time getting back to you and charge you extra to return it. They aren’t worth the time.
